One, you shouldn't bump your threads; it's pompous. The rule of thumb is someone will answer when they answer.

Now, do you happen to have overclocking turned on in Luma settings? If so, turn them off along with any other uneeded patches. It should be common sense to know that games such as SSB that use Extended Memory Mode to run (may) require that extra oomph you're dedicating to the entire OS; Or there is simply a conflict with the overclock+specific games (as stated in troubleshooting anyway).

If you don't have those options enabled, then I would double check the integrity of your SD card, as well as your hardware as this is not a widespread issue. Good luck to you.
